BACKGROUND Field

The present disclosure relates to an image forming apparatus that forms an image on a sheet. The image forming apparatus is used as a facsimile (FAX) machine, a copying machine, a printer, and the like.

Description of the Related Art

An image forming apparatus, such as a printer, has been known as an apparatus for forming an image (printing) on a sheet. One function of the image forming apparatus is a hold printing function in which print data is stored in advance and printing is started in response to a print instruction from a user is known (Japanese Patent Application Laid-Open No. 2013-240929). The image forming apparatus discussed in Japanese Patent Application Laid-Open No. 2013-240929 includes a user authentication function in which the input of a job password for a job password-protected print job for an authenticated user can be omitted.

In the image forming apparatus discussed in Japanese Patent Application Laid-Open No. 2013-240929, only a simple classification, such as an authenticated or unauthenticated state, is used for a user authentication state. However, recently, the office environment in which image forming apparatuses are located has been complicated. In addition, it is common to set a plurality of user authentication levels. Accordingly, it is preferable for each image forming apparatus to be able to deal with a plurality of levels of authentication states. Allowing the omission of a job password in an authentication state with a low authentication level leads to a deterioration in security. Therefore, it is preferable to appropriately make a job password omission setting depending on the authentication level.

SUMMARY

In view of the above, the present disclosure is directed to an image forming apparatus that makes a job password omission setting depending on a plurality of authentication methods.

According to an aspect of the present disclosure, an image forming apparatus that executes a password-protected job to permit execution of printing based on an input of a job password and is configured to permit the execution of the password-protected job based on a specific condition without inputting a job password includes at least one memory that stores a set of instructions, and at least one processor that executes the instructions to manage a first password used for first authentication processing in association with a specific user account, manage a second password used for second authentication processing in association with a specific user account, accept login to the specific user account based on the first authentication processing, permit execution of a password-protected print job associated with the specific user account based on a print instruction without inputting a job password, accept login to the specific user account based on the second authentication processing, and permit execution of a password-protected print job associated with the specific user account based on a print instruction with an input of a job password.

DESCRIPTION OF THE EMBODIMENTS

Configurations for implementing the present disclosure will be described in detail below based on exemplary embodiments and the accompanying drawings. The scope of the present disclosure is not limited to the configuration described in the exemplary embodiments. Part or all of the configuration can be replaced with equivalents as long as similar effects can be obtained.

<Printing System>

In a first exemplary embodiment, a printing system including an image forming apparatus that performs printing using print data transmitted from an external apparatus will be described. FIG. 1A is a block diagram illustrating a configuration of a printing system according to the first exemplary embodiment. FIG. 1B is a sequence diagram illustrating a use case 1 of the printing system according to the first exemplary embodiment. FIG. 1C is a sequence diagram illustrating a use case 2 of the printing system according to the first exemplary embodiment.

As illustrated in FIG. 1A, a printing system 100 (image forming system) includes a personal computer (PC) 101 and an image forming apparatus 102. The PC 101 and the image forming apparatus 102 are communicably connected with each other via a local area network (LAN) 103.

The PC 101 is an information processing apparatus that transmits print data to the image forming apparatus 102. The PC 101 can be replaced by a device (e.g., a mobile terminal or another image forming apparatus) other than a personal computer. The image forming apparatus 102 is an image forming apparatus that forms an image on a sheet based on the print data. In the printing system 100, the image forming apparatus 102 receives the print data, which is generated and transmitted by the PC 101, and performs printing based on the print data. The printing system 100 supports secure printing (password-protected job). More specifically, the PC 101 transmits the print data to which a job password is set, and the image forming apparatus 102, by a user inputting the corresponding job password, can perform printing based on the print data.

The image forming apparatus 102 includes an authentication function and provides a user with various functions based on an authentication level (authentication state). FIGS. 12A and 12B are tables each illustrating relationships between authentication levels and various settings according to the first exemplary embodiment. As illustrated in FIGS. 12A and 12B, the image forming apparatus 102 includes a plurality of authentication methods and setting items for authentication. Examples of the plurality of authentication methods include keyboard authentication and icon authentication as described in detail below. In the present exemplary embodiment, a plurality of authentication levels is allocated based on the authentication method, and the authentication level allocated to the keyboard authentication is higher than the authentication level allocated to the icon authentication. As described above, the image forming apparatus 102 provides the user with functions based on the authentication level. Accordingly, in the printing system 100, as illustrated in FIGS. 1B and 1C, the image forming apparatus 102 is used differently according to each use case.

The use case 1 will be described with reference to FIG. 1B. In the use case 1, in step S111, information indicating that a password omission setting for keyboard authentication is ON and a password omission setting for icon authentication is OFF is preliminarily set in the image forming apparatus 102. In step S112, a user A logs into the PC 101 and issues an instruction to enter a password-protected print job. In step S113, the PC 101 generates password-protected print data, and in step S114, the PC 101 transmits the generated password-protected print data to the image forming apparatus 102. In step S115, the image forming apparatus 102 upon receiving the print data, registers the print job. Then, in step S116, the user A performs keyboard login to the image forming apparatus 102 and selects a print function, and then, in step S117, the image forming apparatus 102 displays a job list for the logged in user. In step S118, the user A selects a password-protected print job from the job list and performs a print instruction. In step S119, the image forming apparatus 102 omits job password input processing based on the setting in step S111. In step S120, printing based on the print data is started.

The use case 2 will be described with reference to FIG. 1C. In the use case 2, in step S151, information indicating that the password omission setting for keyboard authentication is ON and the password omission setting for icon authentication is OFF is preliminarily set in the image forming apparatus 102. In step S152, the user A logs into the PC 101 and issues an input instruction to input a password-protected print job. In step S153, the PC 101 generates password-protected print data, and in step S154, the PC 101 transmits the generated password-protected print data to the image forming apparatus 102. In step S155, the image forming apparatus 102 registers, upon receiving the print data, the print job. Then, in step S156, the user A performs icon login to the image forming apparatus 102 and selects the print function. Then, in step S157, the image forming apparatus 102 displays the job list for the logged in user. In step S158, the user A selects the password-protected print job from the job list and issues a print instruction. In step S159, the image forming apparatus 102 requests the user to input a job password according to the setting in step S151. In step S160, the user inputs the job password in response to the request, and in step S161, printing based on the print data is started.

A combination of alphanumeric characters is used as character types for a user password used for keyboard authentication, while a combination of numbers is used as character types for a personal identification number used for icon authentication. A minimum number of characters for a user password used for keyboard authentication is eight (the minimum number of characters that can be set for a user password used for keyboard authentication is eight), while a minimum number of characters for a personal identification number used for icon authentication is four (the minimum number of characters that can be set for a personal identification number used for icon authentication is four). In this way, a personal identification number used for icon authentication is a simple password with a relatively simpler configuration than that of a user password used for keyboard authentication. Thus, the authentication level of icon authentication is lower than the authentication level of keyboard authentication. In view of this situation, according to the present exemplary embodiment, in the keyboard authentication, which is considered to have a higher authentication level, a setting for omitting the input of a job password can be made, while in the icon authentication, which is considered to have a lower authentication level, a setting for preventing the input of a job password from being omitted can be made. Therefore, according to the present exemplary embodiment, it is possible to improve user operability and ensure security. A configuration for implementing the printing system 100 will be described below.

In a state where the icon authentication setting or the personal identification number utilization setting is OFF, when the selection object 615 is selected on the authentication setting screen 610, a password omission setting screen 730 illustrated in FIG. 7C is displayed. On the password omission setting screen 730, selection objects for setting are masked to prevent a setting as to whether to omit the input of a password from being made.

<Screen Transition>

FIG. 8 illustrates a screen transition. A screen transition to the execution of a password-protected print job in a state where the main body setting is set in the mode 2 illustrated in FIG. 4D will be described below for each of the keyboard authentication and the icon authentication.

First, a case where printing for a job A3 is performed as a password-protected print job for the user A by using the keyboard authentication will be described.

When the user starts the operation of the image forming apparatus 102, a screen 810 is displayed on the display of the operation unit 207. When a selection object 814 is selected on the screen 810, a screen 820 is displayed. The keyboard authentication is carried out on the screen 820. When a user name (user A) and a user password (abcd1111) are input to input forms 821 and 822, respectively, on the screen 820 and a selection object 823 is selected, a login state to the account of the user A is obtained. Then, when the print function is selected on the function selection screen, a screen 840 is displayed. A list of print jobs associated with the user A is displayed on the screen 840. When a job password-protected print job (job A3) is selected from a job list 841 and a selection object 842 is selected, printing for the job A3 is started without requesting the input of a job password (without inputting a job password).

Next, a case where printing for the job A3 is performed as a password-protected print job for the user A by using the icon authentication will be described.

When the user starts the operation of the image forming apparatus 102, the screen 810 is displayed on the display of the operation unit 207. When a selection object 811 is selected on the screen 810, a screen 830 is displayed. A personal identification number for icon authentication is input on the screen 830. When a personal identification number (1234) is input to an input form 831 on the screen 830 and a selection object 832 is selected, a login state to the account of the user A is obtained. After that, when the print function is selected on the function selection screen, a screen 850 is displayed. A list of print jobs associated with the user A is displayed on the screen 850. When the job password-protected print job (job A3) is selected from a job list 851 and a selection object 852 is selected, a screen 870 is displayed to request the input of a job password. When the job password is input to an input form 871 and a selection object 872 is selected, printing for the job A3 is started.

Lastly, a case where printing for the job A3 is performed as a password-protected print job for the user A by using the guest utilization function will be described.

When the user starts the operation of the image forming apparatus 102, the screen 810 is displayed on the display of the operation unit 207. When a selection object 813 is selected on the screen 810, the user can use the function as a guest user. Then, when the print function is selected on the function selection screen, a screen 860 is displayed. All print jobs registered in the image forming apparatus 102 are displayed on the screen 860. A setting for displaying a print job to which a job password is set can be made. When the job password-protected print job (job A3) is selected from a job list 861 and a selection object 862 is selected, the screen 870 is displayed to request the input of a job password. When the job password is input to the input form 871 and the selection object 872 is selected, printing for the job A3 is started.

<Flowchart>

FIG. 9A is a flowchart illustrating print data transmission processing. The processing illustrated in the flowchart of FIG. 9A is executed by the CPU 301 of the PC 101.

When the application 352 for generating document data on an image, a document, or the like issues an instruction to call the print function, in step S901, the CPU 301 starts the reception of a print function operation instruction. First, in step S902, the CPU 301 causes the display device 306 to display a list of printer drivers and receives the designation of a print data input destination. Then, if a detailed setting is instructed (YES in step S903), the processing proceeds to step S904. In step S904, the CPU 301 causes the display device 306 to display the setting screen. If a detailed setting is not instructed (NO in step S903), the processing proceeds to step S907.

If password attachment is designated on a detailed setting screen (YES in step S905), the processing proceeds to step S906. In step S906, the CPU 301 receives the input of the job password. If password attachment is not designated (NO in step S905), the processing proceeds to step S907. After the processing for print setting is completed, in step S907, the CPU 301 waits for an input start instruction. If the input start is not instructed (NO in step S907), the CPU 301 terminates the processing. If the input start is instructed (YES in step S907), the processing proceeds to step S908. In step S908, the CPU 301 generates print data by generating PDL data according to document data generated by the application 352, data on an image or a document, a document attribute such as a document name, a print setting, a user name, and a password. In step S609, the CPU 301 transmits a print job to the image forming apparatus 102.

FIG. 9B is a flowchart illustrating print data reception processing. The processing illustrated in the flowchart of FIG. 9B is executed by the controller 201, more specifically, the CPU 202, of the image forming apparatus 102.

In step S911, the network control unit 256 receives the print data from the PC 101 and delivers a processing instruction to the job management unit 257. Upon receiving the processing instruction, in step S912, the job management unit 257 determines whether a job password is attached to the received print data. If the print data is job password-protected print data (YES in step S912), the processing proceeds to step S915.

If the print data is not job password-protected print data (NO in step S912), the processing proceeds to step S913. In step S913, the job management unit 257 determines whether a print job hold setting is made as the setting for the image forming apparatus 102. The print job hold setting is stored by the storage control unit 255 in, for example, the HDD 205 or the RAM 203. If the print job hold setting is not made (NO in step S913), the processing proceeds to step S918. In step S918, the job management unit 257 requests the job control unit 258 to execute the print job based on the print data and causes the printer unit 211 to execute printing (permits execution of printing). If the print job hold setting is made (YES in step S913), the processing proceeds to step S914. In step S914, the job management unit 257 analyzes the print data and determines whether the print job based on the print data is a hold printing target job. The hold printing target print job described herein refers to a print job in which information attached to the original print data, such as a job name, a user name, and identification information of a transmission source PC matches a predetermined condition.

If the print job is not a hold printing target job (NO in step S914), the processing proceeds to step S918. In step S918, the job management unit 257 requests the job control unit 258 to execute the print job and causes the printer unit 211 to execute printing. If the print job is a hold printing target job (YES in step S914), the job management unit 257 transmits the print job to the data management unit 254, and the processing proceeds to step S915. In step S915, the data management unit 254 analyzes the print data received from the job management unit 257, and extracts bibliographic information.

The data management unit 254 transmits the print data and the extracted bibliographic information to the storage control unit 255. In step S916, the storage control unit 255 stores the received print data in the HDD 205, and in step S917, the storage control unit 255 stores the extracted bibliographic information in the HDD 205 in association with the user.

In the processing of steps S915, S916, and S917, if the processing is unsuccessful, for example, due to an insufficient free space of the HDD 205, the processing is terminated. If the processing up to the registration of the bibliographic information is successful, the print job based on the print data can be registered as a hold printing job and printing can be performed at a timing when a print instruction is received from the user. As described above, a series of processing related to the print job hold setting is carried out.

FIG. 10 is a flowchart illustrating operation reception processing. The processing illustrated in the flowchart of FIG. 10 is executed by the controller 201, more specifically, the CPU 202, of the image forming apparatus 102.

In step S1001, when the user starts an operation on the operation unit 207, the controller 201 starts the reception of the operation. When the operation starts, the controller 201 that functions as the setting management unit 259 checks ON/OFF of the authentication setting. If the authentication setting is ON (YES in step S1002), the processing proceeds to step S1003. In step S1003, the controller 201 causes the operation unit 207 to display the user selection screen 510 for authentication. If the authentication setting is OFF (NO in step S1002), the processing proceeds to step S1016. Then, the controller 201 receives an instruction to select an authentication method by the user.

If the keyboard authentication is set as the authentication method (keyboard authentication in step S1004), the controller 201 causes the operation unit 207 to display a keyboard authentication screen and receives the input of authentication information for keyboard authentication. More specifically, when the button 504 is selected on the user selection screen 510, the controller 201 causes the operation unit 207 to display a keyboard authentication screen and receives the input of authentication information for keyboard authentication. If the authentication is successful (YES in step S1005), the processing proceeds to step S1006. In step S1006, the controller 201 causes the RAM 203 to store flag information indicating a user name and an authentication level 3 and is brought into a login state. If the authentication is unsuccessful (NO in step S1005), the processing returns to step S1003.

If the icon authentication is set as the authentication method (icon authentication in step S1004), in other words, if the selection objects 501 and 502 are selected on the user selection screen 510, the processing proceeds to step S1007. In step S1007, the controller 201 first checks ON/OFF of the personal identification number required setting. If the personal identification number required setting is ON (YES in step S1007), the processing proceeds to step S1008. If the personal identification number required setting is OFF (NO in step S1007), the processing proceeds to step S1013. In step S1008, the controller 201 checks whether the personal identification number is already set in the selected user account. If the personal identification number is already set (YES in step S1008), the processing proceeds to step S1011. If the personal identification number is not already set (NO in step S1008), the processing proceeds to step S1009. In step S1009, the controller 201 receives the setting for a new personal identification number, and then the processing proceeds to step S1011. In step S1011, the controller 201 receives the input of the personal identification number on a personal identification number input screen, checks whether the input personal identification number matches the personal identification number set in the selected user account, and thus determines the authentication. If the authentication is successful (YES in step S1011), the processing proceeds to step S1012. In step S1012, the controller 201 causes the RAM 203 to store flag information indicating a user name and an authentication level 2 and is brought into the login state. If the authentication is unsuccessful (NO in step S1011), the processing returns to step S1003.

Similarly, in step S1013, if the authentication is successful (YES in step S1013), the processing proceeds to step S1014. In step S1014, the controller 201 causes the RAM 203 to store flag information indicating a user name and an authentication level 1 and is brought into the login state. If the authentication is unsuccessful (NO in step S1013), the processing returns to step S1003.

After the login state is obtained through steps S1006, S1012, and S1014, when the execution of the print function is designated, that is, when the button 512 is selected on the function selection screen 520, the controller 201 acquires bibliographic information about the print job associated with the authenticated user.

If a guest user utilization method is set as the authentication method (guest user utilization in step S1004), the processing proceeds to step S1016. In step S1016, the controller 201 causes the RAM 203 to store flag information indicating an authentication level 0. When the execution of the print function is designated, that is, when the button 512 is selected on the function selection screen 520, the controller 201 acquires bibliographic information about all print jobs.

In steps S1015 or S1017, if the bibliographic information is acquired, in step S1018, the controller 201 causes the operation unit 207 to display a list of acquired bibliographic information (e.g., the job list screen 530). Then, in step S1019, the controller 201 executes the print instruction reception processing.

FIG. 11A is a flowchart illustrating print instruction reception processing. The processing illustrated in the flowchart of FIG. 11A is detailed processing of step S1019 illustrated in FIG. 10 . The processing illustrated in the flowchart of FIG. 11A is executed by the controller 201, more specifically, the CPU 202, of the image forming apparatus 102.

In step S1101, the controller 201 receives an instruction to select a print job and start printing on the job list screen 530. In this case, in step S1102, the job management unit 257 analyzes the bibliographic information for the selected print job, and performs job password input necessity result acquisition processing. Details of the job password input necessity result acquisition processing will be described below. In step S1103, the controller 201 determines whether a job password is required based on the acquired result. If the job password is not required (NO in step S1103), the processing proceeds to step S1107. If the job password is required (YES in step S1103), the processing proceeds to step S1104. In step S1104, the controller 201 causes the operation unit 207 to display a screen for requesting the input of the job password. In step S1105, the controller 201 receives the input of the job password. Next, in step S1106, the controller 201 determines whether the input password matches the job password associated with the print data. If the input password does not match the job password (NO in step S1106), the processing returns to step S1104. If the input password matches the job password (YES in step S1106), the data management unit 254 transmits a request for acquiring the print job. Then, the processing proceeds to step S1107. In step S1107, the controller 201 acquires the target print data from the storage destination. The data management unit 254 acquires the designated print job from the HDD 205 via the storage control unit 255. The data management unit 254 transmits the print job to the job control unit 258 via the job management unit 257. The job control unit 258 outputs the received print job to the printer unit 211. In this way, in step S1108, the controller 201 causes the printer unit 211 to execute image formation based on the acquired print data. As described above, a series of processing relating to the print instruction reception processing is carried out.

FIG. 11B is a flowchart illustrating password necessity determination processing. The processing illustrated in the flowchart of FIG. 11B is detailed processing of step S1102 illustrated in FIG. 11A. The processing illustrated in the flowchart of FIG. 11B is executed by the controller 201, more specifically, the CPU 202, of the image forming apparatus 102.

When a print instruction target job is designated, in step S1111, the job management unit 257 acquires and analyzes print instruction target bibliographic information. In step S1112, the controller 201 determines whether the print job is a password-protected print job based on the analysis result.

If the print job is not a job password-protected print job (NO in step S1112), the processing proceeds to step S1109.

If the print job is a job password-protected print job (YES in step S1112), the processing proceeds to step S1113. In step S1113, the controller 201 determines whether the current state indicates that the user authentication is finished. More specifically, the controller 201 determines whether a value other than “0” is set as an authentication level flag. If the user authentication is not finished (NO in step S1113), that is, if “0” is set as the authentication level flag, the processing proceeds to step S1118. If the user authentication is finished (YES in step S1113), that is, if a value other than “0” is set as the authentication level flag, the processing proceeds to step S1114.

In step S1114, the controller 201 determines whether the print job for which printing is designated is a job for an authenticated user. If the print job is not a job for the authenticated user (NO in step S1114), the processing proceeds to step S1118. If the print job is a job for the authenticated user (YES in step S1114), the processing proceeds to step S1115.

In step S1115, the controller 201 checks the authentication level of the authenticated user. If the flag indicating the authentication level 1 is set (authentication level 1 in step S1115), the processing proceeds to step S1118. In other words, if the icon authentication is set as the authentication method and the setting of “make sure to use a personal identification number” is OFF, the processing proceeds to step S1118.

If the flag indicating the authentication level 2 is set (authentication level 2 in step S1115), the processing proceeds to step S1116. In other words, if the icon authentication is set as the authentication method and the setting of “make sure to use a personal identification number” is ON, the processing proceeds to step S1116.

In step S1116, the controller 201 determines ON/OFF of the job password omission setting for icon authentication. If the job password omission setting for icon authentication is OFF (NO in step S1116), the processing proceeds to step S1118. If the job password omission setting for icon authentication is ON (YES in step S1116), the processing proceeds to step S1119.

If the flag indicating the authentication level 3 is set (authentication level 3 in step S1115), the processing proceeds to step S1117. In other words, if the keyboard authentication is set as the authentication method and the setting of “make sure to use a personal identification number” is ON, the processing proceeds to step S1117.

In step S1117, the controller 201 determines ON/OFF of the job password omission setting for keyboard authentication. If the job password omission setting for keyboard authentication is OFF (NO in step S1117), the processing proceeds to step S1118. If the job password omission setting for keyboard authentication is ON (YES in step S1117), the processing proceeds to step S1119.

In step S1118, the controller 201 causes the RAM 203 to store a flag indicating that a job password is required (omission of a job password is not allowed), and then terminates the processing.

In step S1119, the controller 201 stores a flag indicating that a job password is not required (omission of a job password is allowed) in the RAM 203, and then terminates the processing.

The flags stored in steps S1118 or S1119 are used for determination in step S1103.

Advantageous Effects

According to the first exemplary embodiment, the setting as to whether to omit a job password can be changed depending on the authentication method. Accordingly, it ensuring the security and improving user operability can be achieved.

According to the first exemplary embodiment, a job password omission setting for each authentication method can be made. Thus, the setting can be customized depending on the use environment of the user, and therefore excellent usability can be obtained.

In the first exemplary embodiment, if the setting of “make sure to use a personal identification number” is ON in the case of icon selection login, the authentication level is determined to be “2”. In a second exemplary embodiment, it is determined whether to set the authentication level to “2” or “1” based on whether the personal identification number is set for the log-in user, regardless of the setting of “make sure to use a personal identification number”. FIG. 12B is a table illustrating a relationship between authentication levels and various settings according to the second exemplary embodiment. As illustrated in FIG. 12B, in the second exemplary embodiment, even when the setting of “make sure to use a personal identification number” is OFF, if a personal identification number is set for the log-in user, the authentication level is set to “2”. Therefore, when the password input omission setting for icon authentication is ON, the input of a job password for the user whose personal identification number is set can be omitted in printing for the user's print job. The input of a job password for the user whose personal identification number is not set cannot be omitted in printing for the user's print job.

In this manner, detailed settings can be made, thereby improving the user operability and ensuring the security. A printing system 1300 according to the second exemplary embodiment is similar to the printing system 100 according to the first exemplary embodiment, except for the configuration relating to the difference described above. Accordingly, similar components are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

When the setting of “make sure to use a personal identification number” is OFF, the user selects the setting button 514 on the function selection screen 520 to call the setting screen. Then, the user sets any personal identification number on the personal identification number setting screen 630.

FIG. 13A illustrates the configuration of the printing system according to the second exemplary embodiment. FIG. 13B illustrates a use case 1 of the printing system according to the second exemplary embodiment. FIG. 13C illustrates a use case 2 of the printing system according to the second exemplary embodiment.

As illustrated in FIG. 13A, the printing system 1300 includes a PC-A 1301, a PC-B 1302, and the image forming apparatus 102, which are communicably connected with each other via the LAN 103.

The PC-A 1301 is a terminal used by the user A. The PC-B 1302 is a terminal used by the user B. The user A is a user whose personal identification number is already set, and the user B is a user whose personal identification number is not set. The functions and configurations of the PC-A 1301 and the PC-B 1302 are similar to those of the PC 101, and thus descriptions thereof are omitted. In the printing system 1300, a case where the user A performs printing using icon authentication is described as the use case 1, and a case where the user B performs printing using icon authentication is described as the use case 2.

First, referring to FIG. 13B, the use case 1 will be described. In FIG. 13B, steps S1311, S1312, S1313, S1314, S1315, S1317, S1318, S1319, and S1320 respectively correspond to steps S112, S113, S114, S115, S117, S118, S119, and S120. Step S1311 differs from step S111 in that the preliminarily set information indicates that “the personal identification number for the user A is already set and the personal identification number for the user B is not set”. Step S1316 differs from step S116 in that the processing performed in step 13116 is “icon login and print function selection processing”. As illustrated in FIG. 13B, since the personal identification number for the user A is already set, the input of a job password can be omitted.

Next, the use case 2 will be described with reference to FIG. 13C. In FIG. 13C, steps S1352, S1353, S1354, S1355, S1357, S1358, S1359, S1360, and S1361 respectively correspond to steps S152, S153, S154, S155, S157, S158, S159, S160, and S161. Step S1351 differs from step S151 in that the preliminarily set information indicates that “the personal identification number for the user A is already set and the personal identification number for the user B is not set”. Step S1356 differs from step S156 in that the processing performed in step S1356 is “icon login and print function selection processing”. As illustrated in FIG. 13B, the personal identification number for the user B in icon authentication is not set, and thus the input of a job password is required.

FIG. 14A is a table illustrating a user management table according to the second exemplary embodiment. FIG. 14B is a table illustrating main body setting items according to the second exemplary embodiment.

In the second exemplary embodiment, since the personal identification number for the user B is not set, the user management table is as illustrated in FIG. 14A. The second exemplary embodiment is based on the premise that the setting of “make sure to use a personal identification number” is OFF, and thus modes 6, 7, 8, and 9 illustrated in FIG. 14B are set as related setting modes.

FIG. 15 is a flowchart illustrating operation reception processing according to the second exemplary embodiment. In the second exemplary embodiment, even when the setting of “make sure to use a personal identification number” is OFF, if a personal identification number is set for the log-in user, the authentication level is set to “2”. Accordingly, step S1501 is added as a determination flow for the operation reception processing. Therefore, if the personal identification number is already set, the processing proceeds to step S1011. If the personal identification number is not set, the processing proceeds to step S1013.

Advantageous Effects

According to the second exemplary embodiment, additional detailed settings to those in the first exemplary, and thus excellent usability can be obtained.

In the first and second exemplary embodiments, one setting value is set for all users for the job password omission setting. In a third exemplary embodiment, the job password omission setting can be made for each user. Accordingly, the input of a job password can be omitted in printing for a print job associated with the user whose job password input omission setting is turned on, while the input of a job password cannot be omitted in printing for a print job associated with the user whose job password input omission setting is turned off. In this manner, detailed settings can be made, thereby improving the user operability and ensuring the security. A printing system 1600 according to the third exemplary embodiment is similar to the printing system 1300 according to the second exemplary embodiment, except for the configuration relating to the difference described above. Therefore, similar components are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

As illustrated in FIG. 16A, the printing system 1600 includes the PC-A 1301, the PC-B 1302, and the image forming apparatus 102, which are communicably connected with each other via the LAN 103.

The PC-A 1301 is a terminal used by the user A. The PC-B 1302 is a terminal used by the user B. The user A is a user whose password omission setting is turned on, and the user B is a user whose password omission setting is turned off. The functions and configurations of the PC-A 1301 and the PC-B 1302 are similar to those of the PC 101, and thus descriptions thereof are omitted. In the printing system 1300, a case where the user A performs printing using icon authentication is described as the use case 1, and a case where the user B performs printing using icon authentication is described as the use case 2.

First, the use case 1 will be described with reference to FIG. 16B. In FIG. 16B, steps S1611, S1612, S1613, S1614, S1615, S1616, S1617, S1618, S1619, and S1620 respectively correspond to steps S1311, S1312, S1313, S1314, S1315, S1316, S1317, S1318, S1319, and S1320. Step S1611 differs from step S1311 in that the preliminarily set information indicates that “a PW omission setting (for icon authentication for the user A) is ON and a PW omission setting (for icon authentication for the user B) is OFF”. As illustrated in FIG. 16B, since the job password omission setting for the user A is ON, the input of a job password can be omitted.

Next, the use case 2 will be described with reference to FIG. 16C. In FIG. 16C, steps S1352, S1353, S1354, S1355, S1357, S1358, S1359, S1360, and S1361 respectively correspond to processing of S152, S153, S154, S155, S157, S158, S159, S160, and S161. Step S1651 differs from step S1351 in that the preliminarily set information indicates that “the PW omission setting (for icon authentication for the user A) is ON and the PW omission setting (for icon authentication for the user B) is OFF”. As illustrated in FIG. 16C, since the job password omission setting for the user B is OFF, the input of a job password is required.

FIG. 17 is a diagram illustrating a user management table according to the third exemplary embodiment.

In the third exemplary embodiment, the PW omission setting is made for each user, and thus setting values for the PW omission setting are managed in the user management table.

As illustrated in FIG. 17 , a user management table 1730 includes the user name field 431, the user password field 432, the personal identification number field 433, the role field 434, a PW omission (keyboard) field 1735, a PW omission (icon) field 1736. The user name field 431, the user password field 432, the personal identification number field 433, and the role field 434 are similar to those in the user management table 430 according to the first exemplary embodiment. The user management table 1730 differs from the user management table 430 according to the first exemplary embodiment in that the PW omission (keyboard) field 1735 and the PW omission (icon) field 1736 are added.
